SHUT-OFF NOZZLE.

SPECIFICATION forming part of Letters Patent No. 615,434, dated December6, 1898. Application filed July 16, 1897. Serial No. 644,777. (Nomodel.)

To all whom it may concern.-

Be it known that I, WILLIAM F.` CUNNING- HAM, of New York, (Brooklym) inthe county of Kings and State of New York, have invented a new anduseful Improvement in Shut-Off Nozzles, of which the following is aspecification.

This invention relates to an improvement in shut-olii nozzles, with theobject in view of providing a nozzle in which the rotary movements ofthe nozzle-tip serve to open and close the valve for controlling theescape of the Water therethrough.

A further object is to provide a nozzle in which the valve may berapidly and easily opened and closed and yet will remain in Vany desiredposition Without a tendency to change under the pressure of the Waterescaping through the nozzle.

A practical embodiment of my invention is represented in theaccompanying drawings, in Which- Figure I represents a vertical centralsection through the nozzle, the valve being represented as closed. Fig.2 is a transverse section in the plane of the line 2 2 of Fig. l, andFig. 3 is a transverse section in the plane of the line 3 3 of Fig. l.

The nozzle consists of a tapered tip-section A and al base-section B,upon which the tipsection is rotatably mounted.

The nozzle-tip A is provided with a suitable valve-seat a near itsoutlet-opening a'.

The base-section B of the nozzle is provided with a screw-threadedportion b, which is adapted to be engaged with the hose (not shown) forsecuring the nozzle thereon, and the said base-section is furtherprovided with a tapered circumferential seat b upon its exterior, aroundwhich the inner end of the tip A is fitted to rotate. The tip A is heldsnugly in rotary engagement with its base B by means of a sleeve-nut C,which has a screwthreaded engagement, as at c, with the inner end of thetip A, the said nut having an in wardly-extended flange c', which isadapted to impinge against a circumferential iiange b2 upon the base B.

rlhe two sections of the nozzle may be provided with suitablespannerholes or pins. In the present instance pins CL2 b3 are shown, thepins a2 being utilized for rotating the tip A upon its base and the pinsb3 being used for securing the base of the nozzle to the hose andremoving it therefrom.

The valve is of the longitudinal sliding type and consists of acylindrical head D, having a suitable seating-cap d, of disk form, whichis adapted to engage the valve-seat d, an exterior screw-threadedportion d', and an angular shank d2.

The screw-threaded portion of the valve D is engaged by a ring E Withinthe nozzletip A, the said ring being providedwith suitable branches e,extending to the inner wall of the tip, whereby water-exit openings areformed between the ring E and the inner Wall of the tip. The ring E isthus mounted to rotate with the tip A. The angular shank d2 of the valveis shown in the present instance as of squared form in cross-section,and the said shank has a longitudinal sliding movement in a suitableguide F of skeleton form, the arms f of which extend from the portionthrough which the shank d2 slides to the interior wall of thebase-section B of the nozzle. This guide F serves to prevent the turningof the valve D, so that when the tip A is rotated it will force thevalve D longitudinally in one direction or the other to move the valvelongitudinally toward and away from its seat. The screw-threads d uponthe valve-head are preferably of a very considerable pitch, so that alimited rotary movement of the tip A will move the valve longitudinallyto a considerable extent for rapidly opening and closing the same.

. In operation, supposing the valve to be closed and it be desired toopen the same, the tip A is rotated upon its base B, the amount of therotary movement of the tip determining the amount of opening of thevalve D, and p IOO ment of the several parts Without departing from thespirit and scope of my invention. Hence I do not Wish to limit myselfstrictly to the structure herein sept forth; but

What I claim is- 1. A nozzle comprising a base having a guide therein ofskeleton form spaced from its Walls, a tip mounted to rotate on the base-and having a ring therein spaced from its 2. A nozzle comprising a basehaving a guide therein of skeleton form spaced from its Walls, a tipmounted to rotate on the base and having a ring therein spaced from its2o Walls and a valve having a shank annular in cross-section slidingWithin said guide and a head having a screw-threaded engagement with thesaid ring whereby the rotary movements of the tip serve to slide thevalve longitudinally to open and close the same, substantially as setforth.
